MTextView | Android 自绘TextView解决提前换行问题，支持图文混排 | Android library

I got a warning message that says:

[I18N] Hardcoded string "Something : " + someVariable, should use @string resource.

The line of code is: mTextView.setText("Something : " + someVariable);

I usually resolve this problem by extracting it to a string resource like :

mTextView.setText(mContext.getString(R.string.mSomething) + someVariable);

This obviously cannot be used when you have a variables which you want to display. So what is the correct way to display a String resource with a variable without getting a warning?

I've a simple activity, which I want to save it's state on screen rotation, but it doesn't save the state. I have tried to implement the savedOnInstanceState method the way it should be. Do I miss anything? Or it does't work if I get the data from a Web API service.

This the code for the activity. Any helps are appreciated!

I have been working on an app which needed to use CameraX for it's preview stream but it also needs a box kind of overlay from which the text will be decoded. I have successfully implemented the preview but for can't seem to find a way to implement an overlay from which the text will be decoded without using any third party application. Right now we can decode text from the entire screen. I have seen a code that does just this in Codelabs turtorial (link) but it's in Kotlin and I can't decipher this complex Kotlin code. If anyone can help me do this without using third party library,it would be great. Thanks in advance.

my XML code:

I'm currently working on an app in which users can create groups and add members to groups. Today I created a new user to test the app. When I logged in this new user I checked to see if it was a part of any groups, which I didn't expect it to be seeing as it was new. And it wasn't. But then when I logged in my usual user and clicked groups I saw the name of the test user. Why does it appear that this user is a part of a group it was never added to?

It should be noted that when looking through my firebase this test user doesn't appear to have been invited either. I'm using firestore recycler adapter to fetch data in a recyclerView.

Below is the code for my adapter responsible for adding members to a specific group.

FirestoreMemberAdapter.java:

I have implemented a recyclerview, where I want to show the groups that have been created in the app. Right now I am refreshing the recyclerview using the swipeRefreshLayout, but everytime I refresh the recyclerview, it prints out the same group multiple times according to how many times I refresh it.

Can anyone help me solve this problem?

Below is the code.

onCreateView method:

I'm trying to check if there is a value in the shared preference, if not, an Alert Dialog with an EditText will be displayed to add the value.

More so far so good, and displayed and the value is inserted and saved.

More when the application is closed and opened again, it displays the dialog asking again for the value that is no longer assigned to Shared Preference

This is my code:
